介质阻挡放电照相技术的应用

在研究介质阻挡放电照相机理和质量的基础上,采用高压纳秒脉冲介质阻挡放电技术,以硬币、植物叶片以及人体手指为样品,对五种应用实例进行了实验尝试和讨论。结果表明,用该方法在拍摄单一色彩的非平面图案时,所得的图像比用普通光学摄影获得的图像更为完整、清晰、且对比度高。该技术可应用于非平面样品图案图像的提取和复印、植物新鲜程度的鉴别、人体指纹的获取以及特殊摄影等领域。

Lasing on pyroclastic rocks: A case study of <Superscript>40</Superscript>Ar/<Superscript>39</Superscript>Ar dating on Moshishan Group,eastern Zhejiang Province

It is difficult to date pyroclastic rocks, for almost all the dating methods, due to the multiple sources during their formation. ^40Ar/^39gAr incremental heating results on groundmass selected from the samples show that the age spectra are meaningless geologically. However, singe crystal total fusions of CO2 lasing on the sanidine separates could yield rational 4^40Ar/^39Ar results and distinguish their sources in this study. Timing on three formations of the Moshishan Group, after avoiding the exotic and altered grains by lasing on the single sanidine separate, was reported in this paper. The lowermost portion of the Chawan Formation gives an age of 113.7±0.3 Ma; the lower part of the Xishantou Formation was formed 116.4±0.4 Ma ago and the bottom of the Gaowu Formation took its shape at 118.4±0.4 Ma. These new ages are much younger than the previous ones, suggesting that these thick volcanic formations had been formed in very short durations.     

含TiO_2熔渣与铁液之间钛的行为

探讨了含TiO_2熔渣与铁液之间钛的行为,结果表明在试验条件下,钛从熔渣向铁液内迁移时受钛离子在渣中扩散的控制,整个迁移过程的表观级数为准零级,表观活化能为62kcal/mol,讨论了渣中TiO_2含量,碱度,温度等因素对钛迁移量和迁移速度的影响,发现炉渣碱度对钛迁移影响具有两重性:若渣中TiO_2含量较高时(TiO_2>25％),提高碱度将减少钛的迁移量和迁移速度;反之,若渣中TiO_2含量较低时(TiO_2<25％),提高碱度却增加钛的迁移量和迁移速度。     

磷对烃类催化裂化催化剂表面酸性及抗炭性能的影响

考察了磷改性对催化裂化（ＦＣＣ）催化剂的表面酸性、抗炭性及反应活性的影响，探讨了催化剂表面酸性与抗炭性能的关系，结果表明，在以超稳Ｙ分子筛作为活性组分的ＦＣＣ催化剂中引入磷元素，能降低催化剂的表面酸强度，减少酸中心数，降低催化剂的积炭速率，同时加入适量的磷有利于提高催化剂的反应活性。

特异性iRNA应用时机、种类与伤鼠免疫功能变化关系的实验研究

目的探讨伤后免疫核糖核酸（iRNA）应用时机、种类与伤鼠免疫功能变化的关系。方法：将烫伤大鼠随机分成两批9组,采用四甲基偶氮唑蓝（MTT）比色法和3H－TdR掺入法,分别测定各组烫伤大鼠伤后10天时IL-2活性,NK细胞活性和T、B淋巴细胞增殖反应能力的变化。结果：（1）伤后三种iRNA联合用药组NK细胞活性和B细胞增殖反应能力恢复较快,至伤后第10天时分别达到正常的102．0％和95．7％,明显优于单用一种和合用二种组;（2）伤后早期（第1天开始）应用iRNA组IL-2活性和T细胞增殖反应能力恢复较理想,至伤后第10天时分别达到正常的95．8％和98．8％,明显优于伤后2、3、5天开始用药组。结论：伤后尽早联合应用三种iRNA对防止和／或纠正伤鼠免疫功能失常具有重要作用。     

Super resolution reconstruction of moving objects from low resolution surveillance video

Construction of high resolution images from low resolution sequences having rigid or semi-rigid objects with unified motions is often important in surveillance and other applications. In this paper a novel object-based super resolution reconstruction scheme was proposed, in which a six-parameter affine model-based object tracking and registration method was first used to segment and match objects among a sequence of low resolution frames. The motion model was then further extended to the traditional maximum a posterior (MAP) super resolution algorithm. The proposed object tracking and registration method was evaluated by both simulated and real acquired sequences. The results have demonstrated the high accuracy of the proposed object based method and the enhanced reconstruction performance of the extended approach.

摆线等距线齿轮是近年来研制的一种新型齿轮传动。它是利用互为全包络曲线的摆线等距线作为共轭曲线的一种齿轮机构,其特点为:①双摆线啮合;②在节点附近近似面接触;③齿廓间形成包油腔。应用摆线等距线齿轮组成的内啮合一齿差行星减速器与摆线针轮减速器相比,具有效率高、承载能力大和结构简单等优点。本文通过理论阐述和试验结果,证实了摆线等距线齿轮的优点。     

经济全球化与中国法制建设发展的新趋势

经济全球化对世界各国所产生的深远影响已经是不争的事实,但是与此同时区域经济一体化也正显现着其迅猛的势头,各国法律制度都面临着巨大的挑战。面对经济全球化的新形势,法律工作者应具有全球意识、树立世界眼光、正确把握法律的趋同化与国别化的关系,积极推动我国的法制建设,为我国经济的可持续发展提供法律支撑。
